installation method of belt and pulley

Synchronous belt wheel installed on the correct method of synchronous belt and the synchronizing wheel

The correct installation of synchronous belt 

(1) turn off power, remove the protective cover, unscrew the motormounting bolt. Mobile motor synchronizing with enough slack, do not need to open the can remove thesynchronous belt, synchronous belt don't come.

 (2) remove the old belt, check whether there are abnormal wear.Excessive wear can mean the problems of gear design and maintenance. 

(3) timing belt replacement selection. 

(4)clean synchronous belt and synchronous belt wheel, the liquid wiping cloth stained with a little less volatile, soaked in cleaning agent or detergent scrub synchronous belt is undesirable. To remove the oil and dirt, sand or sharp objects scratching, obviously is not desirable. Synchronous belt must be installed before use to keep dry.

 (5)check if there is abnormal synchronous belt wheel wear or crack, if excessive wear, you must replace the belt wheel. 

(6) check the belt wheel is a linear symmetric. Synchronous belt wheel linear symmetrical to thetransmission belt especially synchronous belt transmission device operation is very important. 

(7) check the rest of the transmission parts, such as symmetric bearings and bushings, durability and lubrication condition. 

(8) installed in the synchronous belt wheel synchronous belt is new, not to pry or violently. 

9) tightening gear center distance,until the tension measuring instrument to measure the tension of the timing belts due date. Hand turn coil driving wheel, the tension test. 

(10) device of bolt tightening torque motor, correct. Since any change in center distancetransmission device in operation will lead to bad performance of synchronous belt, it is necessary to ensure that alltransmission parts have been tightening. 

(11) starting device and observe the performance of synchronous belt, to see whether there is abnormal vibration, listen to whether there are abnormal noise, it is best to turn off the machine, check the bearing and motor status; if it feels too hot, may be synchronous belt is too tight, or bearinglubrication is asymmetric, or incorrect.
